In summer, many families have encountered the situation of floor leakage, and serious problems such as sewage overflow and insects crawling out. What is the reason for this?
Originally, the floor drain is the adjacent mouth of the sewer pipe and septic tank and the living room space. The old-fashioned floor drain relies on the water stored by the floor drain to form a water seal, and the living room space is separated from the pipeline system by the water seal. Once the “water seal” is damaged, the sewer and even the septic tank are connected to the indoor space, and the toxic and harmful gases in the sewer such as skatine, carbon monoxide, carbon dioxide, methane, hydrogen sulfide will be emitted to human health.
Countermeasures: When using the floor drain, the water seal must be prevented from drying out, and water should be injected regularly. If you want to last a long time, it is best to seal the floor drain with a lid.
